When creating multibyte or unibyte strings, we should guarantee the
following invariants:
- When creating empty strings, a NULL data pointer should be allowed.
This often arises in practice if the string length isn't known in
advance, and we don't want to unnecessarily trigger undefined
behavior. Since functions like memcpy might not accept NULL
pointers, use the canonical empty string objects in this case.
- Nonzero strings should be guaranteed to be unique and mutable.
These are the same guarantees expected from Lisp functions such as
'make-string' or 'unibyte-string'. On the other hand, empty strings
might not be unique.

Whitespace characters may follow this dot, e.g.,
.include <file>
and
. include <file>
are identical constructs

t.

'buffer-switch': no longer used or defined. (Bug#5803)
A long time ago, `read_key_sequence` used to read the keymaps at the
start, so if something happened between this start and the moment
the user actually hits a key, `read_key_sequence` could end up using
the wrong keymaps. To work around this problem, the code used
`record_asynch_buffer_change` to try and trigger `read_key_sequence`
to re-read the keymaps in some known cases.
Several years ago, `read_key_sequence` was changed so as to read the keymaps
only once the user hits a key, making this machinery now redundant
(and also harmful apparently in bug#5803 because it introduces
"spurious" events).
So we here remove `record_asynch_buffer_change` and the
`BUFFER_SWITCH_EVENT` and `Qbuffer_switch` pseudo-events it generated.
